Application filed January 3', 1922 Serial No. 526,701; I

My invention relates to window-regulators having particular reference tothat type of window used in automobile construction and embodied inautomobile doors such as is shown and described in my pendingapplication for patent Serial No; 396,726 filed July 16, 1920, althoughthis, particular invention is not restricted to such use, :but may beapplied toany window operat-ing mechaw nism whether located in a door orotherwise. The chief objects of my invention are, among other things, toprovide a simple but eflicient connecting device between the :win dowsupporting carrier for raising and lowering the window and thelowerwindow sash,

.whereby the latter maybe readily'disconnected and reconnected to thecarrier proper which is preferably securely afiixed to, and containedwithin, the lower section or well of the door, the upper section orpanel of the door having the sheet of glass maintained therein when thewindow is raised. Should the glass affixed in the movable win dow sashbecome broken, it becomes necessary to remove the sash bodily from thedoor frame,- and to do so the supporting carrier should remainundisturbed in the containing well in the door frame. The aim of myimproved device is to providea simple and cf fective locking andunlocking mechanism by which the window sash may be easily detachedfrom, and attached to, the Windowoperating mechanism withoutnecessitating the removal of the latter from the doorframe along withthe sash, and which may likewise be readily secured and held to thewindow sash through the rotation of the carrier mechanism proper. I

lVith the above and other objects in view,

my invention comprises the novel construction, combination andarrangement of. parts window-regulator as embodied, for example,

in an automobile door, having a vertically slidable upper glass section,the view being taken from the interior, the window-operating mechanismbeing shown in the lower panel;

Similar numerals refer to similar parts throughout the several figures.

Referring to the drawings, the door 7 is as usually constructed for anautomobile body 8 ofthe'limousine type,the door 7 being carried on thebody '8 by hinges-9 as shown in Figure '1. The door 7 comprises ahollowlower section or 'well 10 within which the mechanism for raisingand lowering the window is permanent-1y secured and'contained; The upperdoor section comprises the usual Window glass 11 sliding up and down intheside frames 12 of the door 7, and having the transverse lower sash 13secured to the lower edge of the glass 11 as shown in Fig. '3, wherebythe window is raised and lowered by the mechanism hereinafter to bedescribed.-

At the bottom of the well 10 on the lower frame 14 of the door 7 Isecure in any suitable manner the base 15 from-which the up rightstandards 16 extend vertically, the

upper ends of which are afiixed to'the rec-- tangular plate 17 securedto the inner panel 18 of the lower section or well 10 by screws as shownin Fig. 1. The plate 17 carries the bushing '19 extending through thepanel 18 within which bushing is journalledthe stubshaft 20 to which thehand-crank 21 is'attached on the inner side of the door in any suitablemanner. Secured to the other end of the shaft 20 is the spiral gear 22enmeshing with the spiral gear 23 mounted on the cross-shaft 24journalled in the brackets 25 and 26 atfixed to the inner side of theplate 17, as shown in Fig. 2. The right-hand end of the shaft 24 carriesthe worm 27 which engages with the worm gear 28 mounted on thestub-shaft 29 journalled in the plate 17 and also in the upright bracket30 afiixed to the plate 17v by screws or other'means as shown in Fig. 2.Also mounted on the shaft 29 is the upper sprocket 31 around whichpasses the endless loop sprocket chain 32 V which also passes around,and engages with the lower sprocket 33 carried by the shaft 3 Ljournalled in the base 15 as shown in Fig. 1.

Mounted above the pitch line of the sprocket chain 32 and .securedthereto is the chain block 35 which carries the transverse pin 36 onwhich the roller 37 is mounted to engage in, and coact with, thelaterally extending slot or opening 38 formed'in the jaw-bracket 39which is secured to the lower edge of the window sash 13 of the window11 by screws 40 as shown in 3. On the right-hand side of the plate 17 isthe carrier stop ll having vertical slots d2 formed therei in to containthe screws. a3 by which the stop 41 is slidably mounted on the plate 17.The upper 'end of the stop ell i i rmed with the horizontally-disposedlug la projecting to the left in Figs; 1 ant 5 to engage with the block35 as shown in Figs. 2 and l to hold the roller 37 within the slot 38 ofthe jaw-bracket 39 as shown to operatively con- -nect this bracketsecured to the window sash 11 as shown. The plate l5 shown in Fig. 3prevents the jaw-bracket 39 from spread ing. v

When it becomes advantageous or necessary to detach the window sash 11from the carrier chain 32 without disturbing the mechanism for raisingand lowering the window, the stop 41 is raised either by. hand or anysuitable device to the dotted line position shown in Fig. 5 whichmoven'ient lifts I door 7 for repairs to the glass 11.

the lug 44 not only out of engagement with the chain block 35, but alsoout oi the orbit of this block when the chain 32 is rotated by thehand-crank 21 to carry the block to the dotted line position shown inFig. 5; this chain and block rotating to the right simultaneously causesthe roller 37 to pass out of the open slot 38 formed in the jawbracket39. free from the bracket 39, the Window sash 13 is completelydisconnected from the win-V dow-operating mechanism, pern'ianentlysecured Within the well 10, and the entire and glass may be readilyremoved from the After the Window-sash is replaced in the door When theroller 37 is swung frame 12, the sash 13 may be easily re-con-. nectedwith the carrier chain 32 by reversing the rotation of the latter toforce the roller 37 into the slot 38 in the jaw-bracket 39 as shown inFig; 2," after which the chain stop 41 is lowered to its full lineposition so that the lug 44; engages with the side of the chainblock 3 5to hold the roller 37 in firm engagement with the bracket 39, as shownin Figs. 2 and 4..

It will be understood that the improved window-closure device. hereinshown and tiescribed may be modified and changed in its details withoutdeparting from the; princis ple and scope ofmy invention asparticularlypointed out and defined in the claims.
